Sure, I understand the caution; I'm also willing to consider local
hooks, but given that what I'm doing is attempting to convert the
official Ubuntu live CD builds to live-build, I'd really rather get to
the point where 'lb config --mode ubuntu <some options>' is as close as
possible to the output we have with our previous system, without the
need for custom hooks. Thus, I'm going through the differences between
filesystems generated by the two systems and trying to resolve them.

There's no particular guarantee that mlocate.postinst runs sufficiently
late in the process for the locate database to be reasonably complete
(it would probably be after the bulk of files have been unpacked, but it
would really be better if this were done as close to the end as
possible). Triggers don't really offer the right interface either, and
in any case doing something like 'interest /' in a triggers file would
likely slow the whole process down unreasonably.
